Abstract


The recently discovered phenomenon of the coexistence of a state with charge density waves and superconductivity in the TiSe2CuX system has aroused considerable interest in this material. Following the pioneering work by Morosan et al., this study was performed in search of a better understanding of the superconducting phase of the material. This was done using transport measurements and muon spin rotation .


Samples with various Cu intercalations (X) were measured. It was found that the conductivity, the Hall coefficient, the transition temperature to SC, and the super-fluid density, increase with doping, X. We will discuss our efforts to determine the copper doping and will show that a single gap s-wave SC scenario does not seem to hold for this system .
